At around 9PM me and my co-workers were taking a cigarette break when someone said "what are those lights?" they were traveling in a northern direction and very high. over Hollywood. they were traveling very fast, at that point a helicopter was flying overhead in a westerly direction. the copter gave us an indication that the objects were quite high. They stopped still very north from us. They began to vibrate. And started to switch positions from left to right and vice versa. Then they started to clime in altitude stopping occasionally. This kept on for a few minutes. I ran up strairs to my yell to my co-workers to come and see the event as it unfolded. A total 0f about 8 people witnessed this. The objects the climbed till they no longer were seen. Oh and as they traveled, they were in a triangular formation pointed north.
